Population justification: The global population size has not been quantified, but the species is described as common to abundant (Feare and Craig 1998).
Trend justification: The population is suspected to be in decline owing to trade and to widespread forest destruction, although rates of decline are unlikely to be higher than moderate, as this species is tolerant of secondary and degraded habitats.
